This invention relates tocorrugated sheet building structures in which the sheets are assembled on a frame, and particularly to anv improved sheet fastener whereby the assembling of the sheets is facilitated and the sheetsare held securely'to the frame.

Corrugated materials, such as metal and composition, have been usedheretofore for roofing,siding: and partitions in buildings. The sheets are assembled upon a" suitable frame, usually of metal. To fasten the sheets in place ithas been necessary to employ a. plurality ofbolts, and this has necessitated the drilling of numerous bolt holes in the frame. Theseholes must regis ter with similar holes in the sheets, and" unless the holes'are drilledas the sheets are applied the'lack ofalignment between the holes in the frame and in the sheets usually causes considerable trouble. The drilling-of the frame after it has been erected requires a great deal of costly labor and.theinsertion and securing of the'numerous bolts iscostly and tedious.

'It is the object the difliculties andsome ofthe expense in assembling structures by providing a fast-' ener which can be secured to the sheets be -j fore the latter are placed in position on the frame to securely hold the sheets. in place by resiliently gripping the frame elements.

Further objects and; advantages of the invention will be apparent as it is better understood byreference' to the following specification and accompanying drawin s,

in which Fig. 1 is a vertical sectional view through.

sheets of corrugated material and a supporting angle iron showing a fastener embodying the presentinvention,

Fig. 2 is a perspective view of'the fastening member, and

Fig. 3 is asectional view on line 3-3 of Fig. 1.

In carrying out the invention each sheet is provided with a plurality of fasteners secured theretoin suitably spacedrelation.

Preferably the fasteners are made of metal strap or similar material, and are bent toform a body portion in'whicha bolt hole may be provided with a resilient, section depending 1 from a bent extension of the body. The fastener can besecured to the sheet by a bolt. ;The width of 'the strap should be such that it will rest approxt this invention to avoid: I

' of the sheet material and perforated at 17 matelymidwaybetween the crown and base i of acorrugation in the sheet. The bent exbending the section inwardly'at an acute 'angle to the extension it may be made to I resiliently grip the flangeoftheangle iron so as to draw the sheet against the support v i and to hold it securely in place. a

' In the'enibodiment of the invention shown if sheets 10. Land 10 *of' corrugatedmateria1,

such as. sheet metal or composition material, serving as 'afroofing, siding or partition,

are secured by the fastener-12 to the angle iron 11 7 A bolt 13 having hea'd14 and nut" 15 on'thethreaded end secures the fastener 12 to the corrugated sheets 10 and .10, with l. i

a washer 16 passed over the bolt underthe head where the bolt passes through ahole in: the corrugated sheets. The fastening I member 12 is "formed from strap or'bar iron orsteel of a sufficient width to' lie midway between thebase and crownfof a corrugationv to receive the bolt 13. Thelopposite end 18' of the strapis bent at right angles to. the.

pe'arfo'ratedsection and section 18 is bent in the same direction and at an acute angle to the end 18, forming section 19. The section 19 forms an- 'acute" angle with section 1 81 and will} have a wedging action upon its downward: movement for'securing the sheet i material in position. "As the section 19 proceeds downward with the sheet material attached thereto its wedging contact with I the angle iron will yieldingly draw. the sheet material against the outer surface of the angle iron,'the fastener lyingbetween the corrugations as clearly shown in Fig. 1.- The section of the fastener lying between the corrugations due to the slight flexibility of the metal willbe drawn awa from contact with the sheets if-the we ging action proceeds to extreme.

V The slight spring of the metal described and the inclination of section 19' permits the adjustment of the fastener. to various thicknesses of angle iron. ltrwill be readily seen 'that the'mere lifting of the sheet material will detach .it from the angle iron without the necessity of'removingthe fastening device from the sheet material.

The fastener is usually secured directly through.

The resilient action of the relatively long body portion of the fastener provides a self-adjusting device. If the fastener is bolted to the sheet before it is fastenedto the angle iron support, upon fastening the section in place the section 19 will grip the support with a wedging action drawing the sheets against the support with a yielding grip caused by the resiliency of the body portion in the section 19. If as in some cases it is necessary to place the fastening device on a support as the sheet material is attached, the tightening of. the bolt will draw the fastener to the sheet material and the fastener inturn will resiliently draw the sheet material against the support.

The fastener can be manufactured from strap material, perforated, bent to required shape and galvanized or otherwise coated to preserveit from corrosion.

' I claim:

1; The combination with corrugated sheet material, and a metal support, of a fastening member attached to the corrugated sheet material between the corrugationsby a bolt passing through a perforation in the crown of a corrugation, said fastening member comprising a resilient body portion extending beyond saidmetal support provided with a perforation adjacent its outer end to permit said bolt to pass therethrough, a section bent at a right angleto said'body portion, and a second section bent at an acute angle to said first mentioned section to provide a-wedging member for engagement with said'metal support, said bolt and said wedging member being located at i posite ends of said body portion.

2.' The combination with corrugated sheet material, and a metal support, of a'fastening member attached tofthe c orrugated sheet material between the corrugations'by a bolt passing through a perforation inthc crown of a corrugation, said fasten ng member comprising a resilient body portion having a perforation at its outer end beyond the metal support to permit said bolt to pass therethrough, a section bent at a right angle tosaid body portion, and a second section bent at an acute angle tov said first mentioned section to provide a wedging member for engagement with said metal support, said wedging member contacting with the metal support with a wedging action to resiliently draw the corrugated material into contact with the metal support;

3. The combination with corrugated sheet material and a metal support of a fastening member attachedto the corrugated sheet material between the corrugations by a bolt;

passing through a perforation in the crown :of a corrugation, said fastening member com risin -a relativel 10m resilient bod portion substantially parallel to said sheet through, a section at the opposite end of said body portion bent at a right angle to said body portion and a second section'bent atan acute angle to said first mentioned section providing a weclging member for engagement with said metal "support, the' said wedging member adapted to draw the corrugated sheet material into. binding contact with said metal support.
